platform/x86: wmi: Use ACPI device name in netlink event

The device name inside the ACPI netlink event is limited to
15 characters, so the WMI device name will get truncated.

This can be observed with kacpimon when receiving an event
from WMI device "9DBB5994-A997-11DA-B012-B622A1EF5492":

netlink:  9DBB5994-A997- 000000d0 00000000

Fix this by using the shorter device name from the ACPI
bus device instead. This still allows users to uniquely
identify the WMI device by using the notify id (0xd0).
